Eureka!...

It is so the police can afford to put some go juice in their infernal helicopter and fly it round and round and bl***y round over my house, night after night after interminable night whilst liberally washing everything below in the beam of their 999 billion zillion candle power search light!

I was watching one of those police, camera, action type programmes on TV the other day and they had a child reported as missing. The response was to send the police helicopter out. They didn't know where the child had gone, but thought flying round a helicopter might help. I don't know much about policing, but if that's the threshold required for operating the police chopper than I'm not surprised it's regularly in use...
